Evolution in microstructure and corrosion behavior of AlCoCrxFeNi high-entropy alloy coatings fabricated by laser cladding
TL;DR: In this paper, a model was established to estimate the content of each component in the AlCoCrxFeNi high-entropy alloys (HEAs) coatings, based on which three parameters including mixing entropy, net driving factor and atomic size difference were calculated to precisely predict phase constituents in the coatings.
Journal ArticleDOI
Effect of NiCrBSi content on microstructural evolution, cracking susceptibility and wear behaviors of laser cladding WC/Ni–NiCrBSi composite coatings
X. Luo,J. Li,Guishun Li +2 more
TL;DR: In this article, Ni-based composite coatings were produced on the Ti6Al4V substrate by laser cladding 30.5% WC/70.1% Ni/NiCrBSi.
Journal ArticleDOI
Effect of the scanning speed on microstructural evolution and wear behaviors of laser cladding NiCrBSi composite coatings
TL;DR: In this article, the influence of scanning speed on the dilution rate and microstructure of composite coatings were investigated by X-ray diffraction, optical microscopy and scanning electron microscopy coupled with energy dispersive spectroscopy (EDS).
Journal ArticleDOI
Effect of the content of B4C on microstructural evolution and wear behaviors of the laser-clad coatings fabricated on Ti6Al4V
TL;DR: In this article, the microstructure of the reinforcements in the composite coatings presented the following evolution: hypereutectic consisting of blocky (TiC+TiB2)e eutectics and primary TiCp cellular dendrites (0,wt% B4C), mixture of hypereUTectic and willow-shaped (TiB 2+TiC)p pseudoeutectric (5,wt%, and pseudoeuectic (15 and 25,wt%).
Journal ArticleDOI
Effects of post-heat treatment on microstructure and properties of laser cladded composite coatings on titanium alloy substrate
Guishun Li,J. Li,X. Luo +2 more
TL;DR: In this paper, the effects of post-heat treatment on microstructure, microhardness and fracture toughness of the composite coatings were investigated by scanning electron microscopy, X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), optical microscopy (OM), and wear resistance was evaluated under the dry sliding reciprocating friction condition at room temperature.
